California head coach Mike Montgomery talks with one of the game officials in the first half during an NCAA basketball game against Washington Wednesday Jan 9, 2013, in Berkeley California.

It isn't often a Mike Montgomery-coached squad gets humbled at home, but that's what happened to the Cal men's basketball team Wednesday night as the Bears were pounded in every conceivable way by Washington in losing 62-47 at Haas Pavilion.

Washington played as if its players slammed a few Red Bulls before the game while Cal settled in for a nice pot of Sleepytime Tea.

"There was no energy there," Cal's Allen Crabbe said. "We've got to play with more energy. Myself, I didn't come out with energy. It hurts. It's embarrassing to lose like that on your home floor."

Added forward David Kravish, "We played with no heart, no passion. We had a whole half to come back and play hard. No heart. Couldn't tell you" why.

The Huskies did not take long to demonstrate their superior size, height, athletic ability and aggressiveness as they pulled away from an 18-18 tie in the first half, using a 16-2 run to post a 34-20 lead at intermission. And that was that.

"It was pretty apparent from the start, they were way more ready to play than we were," Montgomery said. "They dominated us physically. ... We kind of caved a little bit to pressure and let them have their way with us."

It didn't get any better in the second half for Cal, a team greatly diminished in terms of depth due to injuries. Regarding Montgomery's bench, there's no there there, with forward Christian Behrens (knee) out for the season and guards Brandon Smith (concussion) and Ricky Kreklow (foot) unavailable for this game.

The loss means a 1-2 start to the Pac-12 season for Cal, which is 9-6 overall. Washington is 10-5 and 2-0. It was a season low in points for Cal and also the fewest at Haas under Montgomery in his four-plus seasons in Berkeley.

Cal needed everything it could get from the conference's leading scorer, Crabbe, but he was not able to respond, harried at every turn by Washington defenders C.J. Wilcox and Scott Suggs. Wilcox led the Huskies with 19 points.

Averaging 21.4 points coming into the game, Crabbe finished with nine. Kravish was Cal's top scorer with 14.

"That's what teams do," Crabbe said. "They try to take me out of the game. It's nothing new. It's been happening all year."

Washington had a huge advantage on the boards, grabbing 48 rebounds to Cal's 33. The Huskies had a 20-11 edge on the offensive glass. Cal further hurt its cause by making only six of 16 free throws.

That this would not be Cal's night was demonstrated when the 6-foot-9 Kravish missed a dunk in the second half.
